Jeremiah is driving from Pensacola to Jacksonville. The graph shows his distance from Jacksonville. What is Jeremiah’s average speed (in miles per hour) during his interval in which he is traveling the fastest? Round your answer to the nearest whole number.
The above amswer is correct

The speed is the change in position divided by the time.
There are four intervals where the speed is uniform:
1) from 0 to 0,5 hours 2) from 0,5 hours to 3 hours
3) from 3 to 4 hours
4) from 4 to 7 hours
We are asked to say the average speed during the interval in which J. is traveling the fastest.
That is where the is more inclined, and that happen in the last interval. There the speed is tha change in position / the time =
(200 -0)miles/3hours = 67 mph.
If you are not sure that this is the fastest speed, you can calculate the speed in the other intervals in the same way and compare.
